Housemate keeps leaving windows open, help?

More of a rant than anything but here goes. I (25f) rent a small apartment with two others who are the same age as me. There are 3 bedrooms, and one kitchen/ living area which is all open plan. My housemate (23m) who doesn’t work keeps leaving 2 of the windows in the kitchen/ living space open all day and by the time I get home from work the place is as cold as it is outside.

During storm Ashley he left the windows open and the place was blown to bits!! Thought I was in the wizard of oz 🙄

A couple weeks ago I politely asked in the house group chat if we could try keep windows/ doors closed to keep the cold out. Housemate (23m) read it and didn’t respond. Other housemate agreed.

Should I send the same text again?? I feel like a broken record. I don’t ever see him in the house because he just hides in his room pretty much all the time.
